Is this a Java bug?

Question

I am confused. Here is the story. I have the following drive and directory structure:
c:\MyDir\check
I have the following two files (mine.java and test.java) in C:\MyDir directory.
package check;
public class mine
public int x = 9;
import check.*;
public class test
public static void main(String[] args)
mine m = new mine();
Here are the steps:
set classpath=.;c:\MyDir;
javac mine.java
move mine.class check (placing the .class file in check directory)
javac test.java
test.java:6: cannot resolve symbol
symbol : constructor mine ()
location: class mine
mine m = new mine();
^
1 error
My solution is when I move mine.java out of c:\MyDir then everything works fine.
Why???

Answer 1

I think it will also work if you change "import check.*;" to "import check.mine;"
The javac compiler automatically compiles dependent classes. Normally this is a helpful feature. In the test class, you reference a class named mine. The compiler doesn't know you mean check.mine because you used the wildcard import statement. So the compiler looks thru the Classpath directories for mine.class or mine.java files. It finds mine.java first and tries to compile it. But, as it compiles, it finds the class is check.mine, not plain mine. So you get an error.
Unfortunately, the error message is somewhat confusing. But, it makes sense to me that you can expect errors if you are going to keep your source code separate from the compiled code, and the source code is in directories where the compiler can find it.
